LAM P-BURNER.

SPECIFICATION forming part of Letters Patent No. 480,404, dated August9, 1892.

Application filed February 25 1892. Serial No. 422,755- (No model.)

T0 on whom it may concern.-

Be it known that I, THOMAS I-IIPWELL, a citizen of the United States,residing at Long Island City, (Astoria,) in the county of Queens andState of New York, have invented an Improvement in Lamp-Burners, ofwhich the following is a specification.

Lamp chimneys have heretofore been formed with a bulb and with anearly-cylindrical base to rest upon the chimney-support and to be heldin position by external chimney-springs, and chimneys of this characterhave sometimes been made with a flattened bulb, the flattening being inthe direction in Which the flat flame is spread, in order that suchflame may not come into contact at its edges with the glass of thechimney.

With chimneys having flattened bulbs and round or cylindrical basesditficulty has been experienced in insuring the proper position of thechimney to the metallic portions of the burner, and when such chimney iscarelessly placed upon the burner the flame is liable to come in contactwith such chimney and break the same.

The object of the present invention is to prevent a chimney beingmisplaced upon the burner; and with this object in View I provide aroundthe cone or deflector a flange or rim notched at opposite edges, and thelampchimney is provided with inwardly-pressed guide-ribs at oppositesides of the chimney and in such relation to the flattened bulb that thechimney cannot be misplaced upon the burner, because the chimney cannotbe set down upon the chimney-rest until it is in the proper position forthe inwardly pressed guides to coincide with and pass into the notchesof the annular flange around the burner.

In the drawings, Figure 1 is a plan View of the burner and a section ofthe chimney at the line 00 a:, and Fig. 2 is a'vertical section of theburner and of a portion of the chimney.

The burner is of any desired character. I have represented the wicktubeA as surrounded by an air-distributerB and a cone or deflector C, andthe chimney-rest D is around the air-distributor B and provided withchimney-springs E, and the annular flange F surrounds the cone ordeflector O, and

it may be either plain or perforated, and there are at opposite edges ofthe annular flangeF notches 2, and the glass chimney G has a cylindricalor nearly-cylindrical base 3 to rest upon the chimney-support D and beheld by the springs E, and the bulb portion 4 of the chimney isflattened, so as to be adapted to receiving the flattened flame of thelamp as it is spread within the chimney, and upon the cylindricalportion of the chimney-base and at opposite sides thereof there areinwardlypressed guides 5, adapted to fit loosely the notches 2 in theannular flange F, and these notches and the inwardly-pressed guides are6 placed in relation to the flat Wick in such a Way that the flattenedbulb of the chimney will have its longest axis in the plane of the flatwick-tube, and should there be an effort to put the chimney on when theflattened 7o bulb is not in proper position for the flame the lower endsof the inwardly-pressed guides 5 Would rest upon the annular flange F,so that the chimney could not be passed down upon the chimney-rest untilit had been sufficiently rotated to bring the inwardly-pressed guides 5into line with the notches 2.

This improvement enables me to make use of a flattened-bulb chimney witha flat Wickburner and flame Without the risk of the flame coming intodirect contact with the flattened bulb of the chimney.

I claim as my invention 1. The combination, with the lamp-burner havingaflat wick-tube and a cone or deflector, of an annular flange aroundsuch cone or deflector, having notches at opposite edges thereof, andthe flattened-bulb glass chimney having a nearly-cylindrical base andinwardlypressed guides at opposite sides thereof to pass into thenotches of the annular deflector, substantially as set forth.

2. The combination, with the flat wickburner having a perforatedair-distributor, chimney-rest, and springs, of a cone or defle'ctor, anannular flange around such cone or deflector and attached thereto andhaving notches in the opposite edges, and a flattenedbulb glass chimneyhaving inwardly-pressed guides at opposite sides to the base thereof,:00

adapted to be reeeivedinto the notches of the of the annular flange,substantially as set annular flange, substantially as set forth. forth.l0
